Abstract
The utility model relates to a speed reducer for a four-wheel drive electric vehicle, which comprises a case body of the speed reducer, an axle I, an axle gear II and an axle II, wherein one side of an output shaft of the case body is sequentially provided with the axle I and the axle II; an oil seal is sleeved outside the axle I, and the outer end of the axle II is provided with a plug and is sealed; one end of the axle I is directly connected with an output shaft of a motor by a spline, and the other side of the axle I is connected with the axle gear II and then connected with a flat key of the axle II; and the outer end of the axle II is engaged with a large wheel. The speed reducer has the beneficial effects that the speed reducer adopts a two-stage expanded helical cylindrical gear speed reduction mechanism inside, and various speed ratios are designed by a method of adjusting the number of teeth, the modulus, the spiral angle and the modification coefficient of the gear, so as to meet the speed ratio requirement of various vehicle types; while different requirements are satisfied, the cost is reduced to the maximum extent, and the waste of resources is reduced; the speed reducer has the characteristics of no abnormal sound, low noise, compact appearance and the high universality; and the bottom can be directly fixed on a vehicle frame, and a matched fixing seat can be selected, so that the bottom can be well connected with the vehicle frame.
Description
Technical field
The utility model relates to a kind of retarder, relates in particular to a kind of retarder that is used for four-wheel driven electric vehicle.
Background technique
The electric motor car industry development is rapid in the market, uses increasingly extensively, and also more and more for the demand of various component, four-wheel driven electric vehicle needs a kind of retarder can satisfy its transmission and matching requirements.In addition, existing similar retarder can't be realized different speed ratios, and noise is bigger, simultaneously greatly degree caused the wasting of resources.
The model utility content
At above defective, the purpose of this utility model provides that a kind of noise is little, external form is compact, highly versatile, can reduce the retarder that is used for four-wheel driven electric vehicle of the wasting of resources, thereby makes and can assemble different gears and the final purpose that realizes different speed ratios with a kind of casing.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of retarder that is used for four-wheel driven electric vehicle, comprise reduction case, axle I, shaftgear II, axle II, output shaft one side of described reduction case is provided with an I, axle II successively respectively, axle I periphery is with oil sealing and an axle II outer end and is provided with blanking cover and seals, axle I one end directly is connected with spline with motor output shaft, axle I opposite side is connected with the flat key of axle II by coupling shaft gear II again, axle II outer end and bull wheel engagement.
The beneficial effect that is used for the retarder of four-wheel driven electric vehicle described in the utility model is: retarder is inner to be secondary expansion helical gear reducing gear, by adjusting the method for the gear number of teeth, modulus, helix angle and modification coefficient, design various speed ratios, thereby satisfy the speed ratio requirement of various vehicles; When satisfying different demands, reduce cost to greatest extent, reduced the wasting of resources; Have have no abnormal sound, characteristics such as noise is little, external form is compact, highly versatile; The bottom directly can be fixed on the vehicle frame, allow the apolegamy fixed base simultaneously, in order to better to be connected with vehicle frame.
